After lock the screen of my o3d and wake it up, the touch panel is very unstable. By using some multi-touch testing app, it can found that the touch panel can only recognize one finger accurately. It there anyone know how to fix this bug????
i did not notice this problem. Try wipe. What firmware you use??
Try to install Android system info. Tap on menu, and touchscreen test. There should be ok.
For me in some testing apps from market, there where some anomalies. Eg. Taping both fingers very fast, and then it recognized only one touch etc.
Seems to happen to me as well on stock 10J Optus Australia firmware. The touch screen seems to be able to detect >10 fingers (Most other smartphones are 3-5) but when more than one is used, the touch points seem to jump to the other finger (For example, in fruit ninja, when two fingers slide vertically quickly, sometimes a random horizontal cut occurs).
Its pretty annoying in games - Especially when trying to shoot and aim in Modern Combat 2, I keep doing 180 degree turns randomly.

Yes I have the same problem in games, sudden180 degree spins in backstab, shadowgun ...
I'm on stock GB.
happens almost everytime screen locks when a game is running. try playing minisquadron and let the screen lock. when you wake phone up only one touch will be recognised at a time for an interval ranging from a few seconds till you shut down the game and restart it or even sometimes restart your phone. had it since v10a all the way to v20a and believe my i tried them all. even on custom roms....
The solution: (kind of)

I thought I was just crazy when this happened.
The 3-tap fix doesn't seem to completely fix it but it helps without having to restart the game.
I've got Xperia J with CM 10, release FXP217, kernel version 3.0.8. Everything seems all right and the phone works as it should (except of the known issues and bugs). But I noticed that nobody mentioned, that their touch freezes or anything.
The main issue and reason for asking this question - sometimes my screen, or rather touch, freezes and there's nothing I can do with it. It doesn't react to any movement, but the phone itself remains functional and does everything normally, so it doesn't remain active or anything, just doesn't react to any touch at all. I have to press power button a lot before it starts reacting again. I usually press the power button and move my finger across the screen for as long as it doesn't lock itself or unfreeze.
At other occasions it does something a bit different - the touch gets a bit dull and unresponsive in general, but after some using it, it goes back to normal. When using the Pointer location overlay i noticed, that while I move my finger across the screen, the trail stops for a half a second or so and continues. It's like the touch periodically gets "disabled" or something. But when I press HARD and move my finger a bit slower than regularly it mostly is good and after some time - it gets back to normal.
One day it may occur twice or maybe even not at all, sometimes it happens a lot, like even 4-7 times; at rare occasions, this problem reoccures in small periods of time (like when I use the touch screen a lot).
Is there anything known about this issue? Is there a fix for that?
So, i have Mi4W for almost 2 years, and now it's touchscreen starting to become unresponsive. Is there something i can do myself about it (without bringing it to service center)?
The problem is minor and only happen sometimes, though mostly when i use it for rhythm game where i need to do fast multiple tap or hold tap. I've tried wiping the screen clean but the problem still there.
HV problem with this device can't play any games when I swipe it's like sensitivity automatically gets to almost a point that touch becomes unresponsive I either have to move finger great distance to reset or retap finger to reset I don't think it's with hardware bcuz at first swipe even small swipe it works fine but then slowly loses sens is there ouch acceleration in this phone help me
I bought this phone the problem is that when i swipe touch slowly decreases to point that screen dosent register small thumb swipes, u know on spot thumb wiggle movement i hv to move more or retap to reset so pubgm cant aim in game cant follow aim to running enemy bcuz in half way sens becomes nill this phone has coloros is that the issue and yes problem is on the main screen so its not problem with game can anyone help me video below https://drive.google.com/file/d/1-8JBHK2MjVd_qvXPZyBkUjbnBAI4BI8x/view?usp=drivesdk
